Paperback. Condición: New. Print on Demand. This book reports on a scientist's expedition to Peru to study the guinea pig in its natural habitat. The scientist aimed to prove his theory that the guinea pig originated in Peru and would provide insights into the origins of domesticated varieties. The book delves into the breeding…experiments the scientist conducted, crossing wild guinea pigs with domesticated varieties to observe the inheritance of various traits, including coat color, eye color, and body size. Through these experiments, the author discovered that the variation seen in domesticated guinea pigs was the result of loss mutations or retrogressive modications, not new mutations. The scientist's work not only provides new insights into the evolutionary history of the guinea pig but also contributes to our understanding of the origin and diversity of other domesticated animals. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
